Nico Landauer is the best rider who competed with an Aero in a major event, he did manage to get a 3rd plance in the pro tour San Fransisco but didn't score high overall due to a failure of his bar. It is competitive for sure against a R1 v2, but the Ozone prototypes Parlier/Lecesse ride and the latest Enata or Sonic race are maybe a little faster.
It all comes down to who gets the best riders in their team, PL is woring on it myself included. I hope to have trained enough this year to come close to the top 10 next year, I need to challenge myself more because winning national races with a 60s lead over the rest becomes a bit too easy.
